A little more info on the Stealth V1 mounting.....
The rear deck and 3rd brake light are cardboard and plastic, respectively. Radar attenuation (X, K and Ka bands) is about 1% or so. Whenevery you have a mounting around metal, that's when you have problems because radar doesn't go though metal. The only thing you lose by that mounting is laser protection which is a joke anyway.

Regarding disassembling the V1, I don't think you can do it with success. There is special shielding (which makes it invisibile to the VG2 Radar detector-detector), and if you take it all apart you would produce signal leaks.

My front and rear coverage is still as good as front windshield mounting, except I don't have to ever worry about cops peering in my car or thieves stealing my unit when I'm in the grocery store.

Good luck!
